After contracting tropical pneumonia on a family vacation to the Dominican Republic and getting a taste of his own mortality, author A.J. Jacobs decides to go on a two year quest to become the healthiest man alive. Jacobs decides to go about this by tackling one body part per month. He starts with the stomach and finishes up with the skull. Along the way, he focuses on everything from the adrenal gland (lower his stress levels) to the skin to the hands. Throughout the book, Jacobs shares interesting studies that have been conducted about health and we learn how many health claims by “experts” are dubious at best. Jacobs approaches the topic of his own health with skepticism, humor, and a willingness to try new things in the name of trying to become the healthiest man alive. He obviously doesn’t make his goal, but he learns a lot along the way (and shares it with his readers). This isn’t a how-to-manual, but the quirky story of Jacobs’ experiences and the many people he meets along the way as he tries to improve his health.
